How to Disable Windows 11 Defender: Temporary and Permanent

Microsoft Defender Antivirus is the built-in security solution for Windows 11, protecting against viruses, malware, and ransomware. Users may need to disable it temporarily or permanently for various reasons, including software installation, penetration testing, performance issues, transitioning to third-party antivirus solutions, or troubleshooting conflicts. Temporary disabling can be done through the Windows Security app, which will automatically re-enable after a restart. Permanent disabling requires changes in Group Policy, applicable only to Windows 11 Pro, Enterprise, and Education editions, and necessitates disabling Tamper Protection first. Another method for permanent disabling is installing a third-party antivirus, which automatically deactivates Defender's real-time protection. Windows 11 Home users cannot use Group Policy for permanent disabling but can still temporarily disable Defender or install a third-party antivirus. Disabling Defender exposes the system to threats, and users should ensure they have alternative protection in place. Major Windows updates may reset Defender settings, and caution is advised when modifying system settings.

Google warns millions of android users as virus spreads via WhatsApp, Instagram, Facebook, YouTube and more Apps; How to stay safe

Google has issued a warning to Android users about a dangerous malware called Arsink Malware, which is a Remote Access Trojan (RAT) capable of stealing personal information and taking control of infected devices. It spreads through apps that appear legitimate, often masquerading as "Mod" or "Premium" versions of popular applications. Arsink malware typically infiltrates devices via Telegram channels, Discord posts, third-party websites, and suspicious download links. Google has confirmed that no versions of Arsink are available on the Play Store and that devices with Google Play Protect enabled are automatically safeguarded against such threats. Google is also working with researchers to dismantle the infrastructure associated with this malware. To stay safe, users are advised to download apps only from the official Google Play Store, avoid 'Mod' or 'Premium' versions of apps, refrain from clicking on suspicious links, carefully check app permissions, keep Google Play Protect enabled, and regularly update their devices for security patches.

Android users warned about new bug that steals private data – which apps to delete

The Arsink malware is an Android Remote Access Trojan (RAT) that exfiltrates sensitive information while granting remote control to its operators. It has impacted over 45,000 devices in 143 countries, including the UK. Arsink lures users to download deceptive "pro" versions of popular applications, often promoted on social media instead of the Google Play Store. Once installed, it can access text messages, emails, call logs, contacts, microphone recordings, photos, location data, and more. The malware also allows hackers to control device features such as using the torch, playing audio, making calls, and changing settings. It hides its icon, runs a persistent foreground service, and generates notifications to avoid detection. Users are advised to remove any "pro" versions of well-known apps like Google, YouTube, WhatsApp, Instagram, Facebook, and TikTok that are not from the official Google Play Store.

Not a virus: What it means and why antivirus flags it

The term “not a virus” is used by antivirus software to indicate that a file does not match known malware signatures but still triggers a detection. This means the file is not automatically blocked or confirmed as a threat; the alert highlights something unusual, leaving the decision to the user. Alerts typically arise when software exhibits behavior associated with increased risk, despite lacking clear evidence of malicious intent. Malware is specifically designed to inflict harm, while files labeled “not a virus” may perform actions that raise security concerns but are not classified as harmful. Antivirus programs identify threats through signature detection and heuristic behavior-based detection. Legitimate programs, such as system utilities, download managers, and game cheats, can inadvertently trigger “not a virus” alerts. Common types of detections include adware, riskware, and potentially unwanted applications (PUA). The primary security risk of “not a virus” files is exposure rather than direct attacks, and privacy concerns often arise from data collection by these programs. If an antivirus detects “not a virus,” users should identify the file, review recent changes, compare detections, and decide whether to keep or remove it. To reduce unwanted alerts, users should download from official sources, use custom installation options, and remove unused software.

This day in history: The first computer virus hits the world

On January 19, 1986, the computer virus Brain emerged, recognized as the first major global threat in cybersecurity. Created by Basit and Amjad Farooq Alvi in Lahore, Pakistan, it targeted IBM PC-compatible machines running MS-DOS and spread via floppy disks. Brain was initially intended to protect the brothers' medical software from piracy by tracking unauthorized copies. It embedded itself in the boot sector of infected computers and displayed a message with the creators' contact information. Despite its benign intent, Brain spread internationally, highlighting the potential for software to replicate and traverse borders autonomously. This event raised awareness about computer viruses and initiated discussions on antivirus solutions and the ethical responsibilities of programmers. Brain exposed vulnerabilities in early personal computers and prompted the integration of cybersecurity considerations into software design.

Quarantine Zone: The Last Check review

Players assume the role of a zombie plague "doctor" in the first-person simulation game Quarantine Zone: The Last Check, set to release on January 12, 2026, for £17. Developed by Brigada Games and published by Devolver Digital, the game allows players to screen survivors at a military outpost during a zombie apocalypse, ensuring they are free from the zombie virus and other ailments while also checking for hidden explosives. Players examine survivors for signs of infection, using various tools to inspect their bodies, but the repetitive nature of tasks may lead to monotony. Additionally, players manage supplies and upgrade tools, although these tasks lack depth. Occasional minigames provide brief diversions, but the core gameplay focuses on conducting medical exams. The game will be available on platforms like the Steam Deck.
